Wausau, Wis. (Jan. 2013) – Demonstrating its custom capabilities to visitors at the 2013 International Builders' Show in booth #C2607, Kolbe showcases a multi-slide door of significant scale and sophisticated style.

This new Ultra Series multi-slide door upgrades standard patio door openings without requiring a full wall system renovation. Stretching up to 24 feet wide and 10 feet high, the new product accommodates as many as six 48-by-120-inch panels that can stack or pocket. Upon request, the door also can be manufactured as a custom corner unit. Various stile and rail options and panel thicknesses are available, including narrow stiles for a modern aesthetic.

The multi-slide door model on display at IBS 2013 features a low profile sill for a smooth transition between interior and exterior spaces. On the exterior, the display unit is clad in low-maintenance extruded aluminum with recycled content, finished in blue-gray Cape Cod. For the interior, Rustic Umber hardware accents pine painted in Natural Cotton. A range of sustainably harvested wood species can be selected for the interior, such as those certified by the Forest Stewardship Council™ (FSC® license code FSC-C019541).

A range of glass choices are offered to enhance the environmental and energy-efficient attributes in different U.S. regions. Regardless of climate zone, Kolbe products also support projects pursuing green goals including U.S. Green Building Council's LEED® Rating System™, Green Globes™ and ENERGY STAR®. Helping design teams with their product selections, Kolbe's website offers air, water, structural and thermal reports; warranties, installation and maintenance information, and online videos to demonstrate product operation and performance testing.
